Release Notes
Avalon 6.5 includes IIIF manifest generation, a new editor for structural metadata, and integration with the Timeliner tool for annotation of AV materials, as well as a variety of updates for supporting libraries and components.
Features
Structural Metadata Editor
A visual editor for creating and modifying section structure available on an item's Edit page. The new editor features a waveform visualization and interaction much like audio editing software such as Audacity or Adobe Audition.
IIIF Timeliner
Integration with Timeliner, a reimplementation of the Variations Audio Timeliner annotation tool. Create, edit and share Timelines using media from items within Avalon.
IIIF Presentation 3.0 Manifest Generation
IIIF manifests are now generated by Avalon for all items and can be retrieved from an application endpoint.
Updates and Bug Fixes
...
7.0 is a major release with changes relevant to end users, collection managers and system administrators.
Features
Collections Index and Collection Landing Pages
Avalon 7 provides two new ways to explore and display collections: the collections index, a listing that shows each collection accessible to a user sorted alphabetically or by containing Unit, and collections landing pages, which provide a unique page for each collection where users can view a description, thumbnail and a preview of items within. Collection managers can now set thumbnails for collections as well as items.
Transcoding Pipeline
With this release of Avalon, the transition from Matterhorn to a self-managed transcoding process has been completed. Using the latest version of active-encode and the FFmpeg adapter, transcoding tasks are faster, leaner, and more flexible. A new transcoding dashboard also provides administrators a way to manage jobs directly within Avalon. While Matterhorn is no longer supported, full support is available for Amazon's Elastic Transcoder service.
New Homepage Design
Avalon's homepage has been redesigned. In addition to the visual change, Avalon allows for easy configuration of the featured collections now displayed on the homepage. The Avalon 6.x-style homepage can also still be used if desired.
Local User Management
A new authentication configuration is available through Persona. This module allows for administrators to quickly create user credentials without relying on an outside authentication system (LDAP, Shibboleth, etc.).
Updates and Other Changes
Sidekiq
The performant, feature-rich, and better maintained Sidekiq replaces Resque as our default background job engine. This aligns Avalon with most Samvera applications, including Hyrax, which have already made this switch.
MinIO
It is now possible to use a MinIO object store to avoid a shared storage requirement and decouple Avalon, Worker, and Streaming services from each other in alignment with 12 factor best practices.
Avalon API
The Avalon API has been updated to allow for access to resources based on system role. API keys issued to users now gate requests to permissions a user has within the system, rather than providing superuser rights for each issued key.
Bug Fixes
- Multiple styling issues on mobile browsers resolved
- Structural Metadata Editor now properly handles certain timecode formats in existing structure
- Caption files with empty terminating time ranges display properly when enabled
